“…Stretchable strain sensors have attracted extensive attentions due to their potential applications in a variety of fields such as flexible electronics, − soft robotics, , and health monitoring. − In recent years, massive efforts have been devoted to develop flexible strain sensor with combined superiority of flexibility, broad sensing range, high sensitivity, and mechanical stability of the strain sensor. − To date, it is still a great challenge to fabricate strain sensors with simultaneous large workable strain range and high repeatability. Low detection limit, which is one of the key indicators of a strain sensor, as well as the maximum detection strain is equally important in expanding the workable strain range.…”

Flexible strain sensors have attracted extensive attention in electronic skins and health monitoring systems. To date, it remains a great challenge for the development of a multifunctional strain sensor with simultaneous ultralow detection limit, broad sensing range, and high repeatability. In this paper, we report a new carbon nanotube/flexible fibershaped strain sensor. The fiber substrate has a novel microstructure where a highly elastic rubber fiber core is tightly wound by a continuous spring-like polypropylene fiber as the shell. Our sensor offers combined sensing performances of ultralow detection limit of 0.01% strain, wide sensing range of 200% strain, and high repeatability of 20 000 cycles by designing doubleleveled helical gaps. This strain sensor shows a rapid response time of 70 ms under both stretching and releasing. In addition, it is available for a variety of other deformations such as bending and torsion. Due to the unique fiber structure, it can extend the torsion detection range to 1000 rad m −1 . On the basis of the superior sensing performances, our sensor demonstrates to efficiently work for both subtle physiological activities and vigorous human motions. This work provides a general and effective strategy for designing smart wearable devices with high performance.

“…Despite these considerable achievements in stress and strain sensors, the construction of a stretchable multimode mechanical sensor capable of sensing pressure, strain, and flexion for monitoring human body motions ranging from subtle deformations to substantial movements remains a challenge. , Ge et al reported an electronic fabric with the ability of simultaneously mapping and quantifying mechanical stresses induced by pressure, lateral strain, and flexion. The fabric was based on intertwined sensor electrodes with piezoresistive rubber as the shell sensing element and silver-nanowire-coated elastic thread as the stretchable and highly conductive core electrode …”

The development of flexible and stretchable electronic skins that can mimic the complex characteristics of natural skin is of great value for applications in human motion detection, healthcare, speech recognition, and robotics. In this work, we propose an efficient and low-cost fabrication strategy to construct a highly sensitive and stretchable electronic skin that enables the detection of dynamic and static pressure, strain, and flexion based on an elastic graphene oxide (GO)-doped polyurethane (PU) nanofiber membrane with an ultrathin conductive poly(3,4-ethylenedioxythiophene) (PEDOT) coating layer. The three-dimensional porous elastic GO-doped PU@PEDOT composite nanofibrous substrate and the continuous self-assembled conductive pathway in the nanofiber-based electronic skin offer more contact sites, a larger deformation space, and a reversible capacity for pressure and strain sensing, which provide multimodal mechanical sensing capabilities with high sensitivity and a wide sensing range. The nanofiber-based electronic skin sensor demonstrates a high pressure sensitivity (up to 20.6 kPa), a broad sensing range (1 Pa to 20 kPa), excellent cycling stability and repeatability (over 10,000 cycles), and a high strain sensitivity over a wide range (up to approximately 550%). We confirmed the applicability of the nanofiber-based electronic skin to pulse monitoring, expression, voice recognition, and the full range of human motion, demonstrating its potential use in wearable human-health monitoring systems.

In article number 1902883, Muhammad Mustafa Hussain and co‐workers demonstrate a lithography‐less, cost‐effective process for the fabrication of monocrystalline silicon solar cells which is complementary metal oxide semiconductor (CMOS) technology compatible. This technique uses an alternative pattern of corrugation that enables the crystalline silicon based solar cells to retain 20% or higher photovoltaic efficiency while making it ultra‐flexible (1.4 mm bending radius) and record stretchability (up to 95%).
